Is your laptop working normal just with the battery? if it is remove the battery and try to power up the laptop with the power supply if shuts down have some one test the power supply for a short in it and the plug in part of the loptop.very posible there is a short in the line that connects the power supply.

Do you get any error-beeps of any kind? Like the battery is going empty? Or does it just go off suddenly? If the first is the case, your power connector in the computer or perhaps the powersupply could be broken. It could sound like your battery doesn't get charged and your computer isn't getting power. Then it will shut down. See if the power/charge indicator is on when connected to the power grid.
If it blacks out suddenly it's probably a more severe problem, but you might try to reinstall the OS (I'm guessing windows), but only as a last resort.

you need do check:
1) no charging means adapter input problem, first check your adapter DC output voltage is ok
2) check DC jack socket on the motherboard:
--- DC socket any pin disconnected, you need use iron and flux to fix it
--- DC socket damage(broken),you have to change it
3) if DC socket connection normall, the DC/DC circiute near around DC socket some component damage, you need find a technacian to repair.
hope help you to deal it well

You probably have a clog of dust between the fan and the heatsink. It would be best to have it disassembled to clean, although a few models have clean-out doors to the fan on the back. You might be able to somewhat clear it by blowing canned air in the vent, but this may push dust balls into the fan that go right back against the heat sink.

Mine did this and I thought it was overheating and vacumed the back vents. This fixed the problem.
